In the thermoforming packaging production process, various issues frequently arise. Common problems include stringing, scratches, crystallization spots, bubbles, and water‑ripple patterns. These defects can significantly compromise the quality of thermoformed packaging products. Today… Blister packaging processing Here’s a brief explanation of how to address water‑ripple defects in blister packaging, with the hope that it will be helpful.
1. Modify the thermoforming mold: Change the entire smooth surface to a textured, dimpled surface; this will significantly reduce water‑ripple defects in thermoformed packaging products.
2. Modifying the thermoforming mold: The most commonly used thermoforming molds are copper and aluminum molds. Because both have relatively smooth surfaces, they tend to produce pronounced water‑ripple defects. In such cases, it is advisable to switch to resin molds, which are seldom employed but, with their rougher surface, are highly effective in mitigating water‑ripple issues.
3. Switching to a Different Machine: Blister packaging production typically relies on high-speed thermoforming machines, which offer stable output and fast cycle times—making them the standard choice for this process. However, when dealing with molds that produce water‑ripple defects, their performance can be subpar. In such cases, a single‑station machine, seldom used in routine operations, comes into play. Because this type of machine employs a batch‑processing approach with slower cycle times, it proves highly effective at eliminating water‑ripple issues.
